PAPER BOX.

Specification of Letters Patent.

PateiitedFeb. 17, 19261.

Application led July 16, 1919. Serial No. 311,142.

l tended lfor application to the type of box usually referred to as knockdownv paper boxes and preferably Amade from a single sheet of box-board'of suitable shape, scored and creased .in such a manner as to form panels, flaps and tucks, to enable the blank to be folded to form vthe completed box. T he invention has particular reference to that class of 'paper boxes which are provided with supporting portions to enable the box to be set up for display purposes in an inclined position, somewhat after the manner of an easel, the said support being of such form andconstruction that itmay be folded flat when the box is in its knockdown form yand which when the box is set up may be locked securely torprevent the easel support from becoming accidentally displacedV or slipped out of position, and yet which may be again knocked down without lmutilation of the parts if desired to repack the box for shipment or for compact storage. The present invention relates to the said support and the lock therefor.

Inasmuch as the invention is intended to be applied more particularly in the construction of knockdown boxes of the character above mentioned, the drawings illustrate and the specification will vdescribe a box of that type although it is to 4be distinctly understood. that the invention is` not intended to be limited to the application to a box as a whole constructed exactly as the one hereinafter described, nor necessarily to a box in .which the body is entirely of a single sheet of-material, nor even to a box in whichv 4at the close of this specification.

Figure l is a plan view of a blank from which a box embodying the invention may be made.

Fig.l 2 is a bottom plan view of the boxv l made out of the blank shown in Fig. 1 in its knockdown form.

Fig. 3 is a sectional view of the box after it has been fully set up and with the easel support locked in operative position.

Fig. 4: is a bottom plan view of the fully set up box shown in Fig. 3. Fig. 5 is a section on line 5 5 of Fig. 3.

Although the body portion of the box is not of itself the subject of the present invention, it will be briefly described in order to4 lead up toand make more clear the invention of the support or easel member and the locking arrangement therefor.

Referring to the drawings, and especially to Fig. 1, the dotted lines therein indicate plie creases; the slits are indicated by full mes. marked to indicate the respective portions of the box which is to be formed out of the blank. There is an inner bottom portion 11, under bottom portion 12 and a display portion 13. Immediately adjacentthe underbottom portion 12 on opposite sides thereof are the two outer side forming portions 141-44, which respectively are connected at their outer edges with inner side forming portions 15-15. One of-these inner side portions is connected at its outer edge with said inner bottom portion 11, andthe other inner side portion 15 is connected with a glue flap 16.

An inner end portion`17 is connected at one edge to thevinner bottom 11, and at 'its opposite edge is connected to the display surface 13. An outer ,end portion 18 is connectedat onel end to the-left-hand outer side portion 14, the other end of said end portion being connected with an end tuck flap 19.

The opposite end of the box is formed by an outer end portion 20, an inner end portion 21 which is Connected with the outer edge of said end portion 20, and a holding vflap 22 which is .formed as an extension of connected a substantially vertical support portion 23 which forms the upright portion of the easel. An extension from said vertical support portion 23 forms the bottom supporting portions 24 and 25 which are The several portions of the blank are,

portion 26 having one or more side wings 47, 47. Preferably there are twosueh wings, one on each-side.

more side wing portions 40e-.#10, which at their ends are separated from the bottom support member-2at by slits 41, and are separated from the tuoklportion 26 by slits412,

l so 'that these side wing portions O-il() may "be turned up at an angle to the bottom support member 24, or if desired they may be A allowed'to lie'in the same plane with the support member 24 .according to the requireni'ents .as will be more particularly hereinafter described.` Preferably there are two. of these wings 40, one on each side.v Grease lines 48 Aalong the junction line between 'the wing portionsLlO-AOand the bottom support 25 and creaselines L16 between the b'ody 'of the lock member 26 and its wing portions 47 lform the bending line of said wing por-.

The purpose of said shoulders The tuck member 26 with itswings is'A broader than the neck portion. 25 of the bottom support member, that is broader than that portion of the bottom support 25 which lies between the wings l0-10, forming the shoulders #P1- 44' where said tuck member 26 s offset .from the bottoni support meinT V portion of said bottom support member 25 support vmember 24, forming shoulders '4t-44 and L5-415 is Ato limit the sliding movement ofthe vertical aiidbottom supports as will be hereinafter more particu- -larly described.

, From the bottom 12 lthere is preferably-- died out a reinforce member 28 creased at 6() to engage with aslot 34' when the'boxisset up. t

The outer sides lik-'H are provided with tuck flaps 30-31 and the inner sides 15415 are provided with flaps 32f33 respectively,

whichv when the boX isset up are folded against the inner face .of the inner end member 17 while the outer end member 18 is folded outside of the endv member 17 In making up the box from the blankv after the blank has been died out, the lowei` bottom 12 is formed with a .slit c transversely thereof, which-is of a width ap- `vproXiinately equal to or slightly greater' than-the width oftliat portion of the bottomsupporting member 25 which liesbe -tween the wing portions 40-40 -By folding the Wing portioiis'llO-fiO llat over onto the under surface of the supporting member 25, and by folding the side wing p0rtions of the tuck member along the.

l is narv rower than the adjacent end ofthe bottoni' up against the under surface of the body portionof saidtiiok lmember 2,6, the said tuck member'26 and the supporting meminay be passed through the said slit 'and l pushed. in iintilthe botto-m supporting por- The botteln support portion 25 has one or tion 24' and the vertical supporting portion 23 lie flat up .against-the under side of the lower bottom portion 12 while the supporting portion 25 and the tuck member 26 lie between the inner bottom 11 andl lower bot- .'tomf12. Thewing portions 47447 of the tuck 26 'are ythen spread out .flat in the"` same plane as the body of the tuck, as sho-wn in Figi 2. This is'more conveniently done before the sides andin'ner bottom are folded.

'These wings 47%7 serve as locks or stops to -limitl the sliding movement of the bottom support in ember'25 and to prevent its be- 'ing again accidentally withdrawn.

The

combined members 25; and 26 with their l wings. 40 and 17 is for-convenience referred to as a tongue when it is desired to speak of it as a whole.

V4The blank is then folded along thelines n. and Z) to 'superpose the inner sides 15-15 on tlieouter sides 14414 and also to superpose the inner bottom 11 on the lower bottom 12. The left-liandinner side 15 'will vbe Afolded before the right-hand-inner side '15 So as' to bring the glue flap 16 in between theinner bottom 11 and the lower;

der side of the inne-r bottom 11. The double sides formed by folding the inner sides 15 'over on t'o the inner face of the outer sides 1i are then turned up into a vertical position-at right angles to'the bottom portions 11-12, and the vflaps 32 are turned in; the `inner end 17 with the displayv surface 13 attached thereto is then turned up into a 'vertical position and lies in Contact with the flaps 32 The outer end 18'is'theii folded over Aonto the inner end 17 and the .fully folded 'as already described, the tuck member 26` the bottom supporting portion 25. and the bottom supporting portion 24 and the vertical supporting member 23 all lying flat in the saine plane..the said bottoiii supporting portion v25 andthe tuck.

portion 5 26 are still inclosed between' the inner and lower bottom: portions 11-12, asy

bottom 12. The so-called'glue flap 16-may I -or may not be glued as desired, to the unioo Aend .tuck 19 is inserted betweenvo'ne set of -vertical supporting member28, and pulling out the supporting member25 from its inclos'ure between the two bottom members 11h12 until the shoulders of the wing members 4-7-47 of the tuck member 26 strike the edges of the slot c to prevent the further *withdrawal This outward movement, however, is sufficient to withdraw the wing membersv 40%() of the supporting member 25 entirely out of the slot, they being separated from the wing members of the tuck bya slit, and'said wing members @l0-l0 can then be lturned into angular rela-tion to the supporting member 25, as shown in Figs. 3 and 4.

.The ends of said wing members 40-40 then serve as stops to prevent the said bottom supporting portion 25 from being pushed back again through the slot c, so long as the said wing members 40-40 are left in their angular position with relation to the said portion 25.

The easel supportfor the box is thus formed by the combination of the two bottom supporting members 25 and 24. and the vertical supporting member- 23 as shownA in Fig. 8. The easell 'is locked in this position by reason of the' vfact that the wingmembers lO-40 prevent the bottom support 25 from being pushed in again `through the .with only one wingthe look slot c, and the laterally extending wing members 47, of the tucks 26, which are still in between the t\wo bottoni forming lmembers 11-12, engage the edges of the slot on the inside to prevent the further outward withdrawal of the easel. As previously stated, there are preferably two wing 'portions 4:0V and two wing portions 47, but if the tongue 25 and the tab 26 are each provided will be fairly f effective and will come within the scope of the invention, and is intended to be covered by the claims. y

If for any reason it is desired to recol- 'lapse the box, the wing members iti-10m ay be turned up aga-inst the under side of the portion 25 so as to allow the portion 25 to-` gether with the turned under members -lO-Ll-O to be pushed into the slot c, and then the whole easel formed by the combined members previously referred to may be lattened out against the bottom of the box. If it is then desired to recollapse the entire box, it is evident that this may be done by reversing the steps by which the box was set up in a: manner which will be well understood.

It will `be obvious that the easel portion of the box together with its locking connec- 'after insertion serving as a whenthe wing nearer the end of the tions may be applied to a. paper box having a slit in the bottom to receive the locking mein-ber although the body of the box nn.

.be varied in its form of construction in l,

great variety of ways. It is not even vessential that the box should have a double bottom. although this is preferable for the purpose of protecting the locking member.

lVhat- I claim is ing a bottom formed with a slot therein, an easel therefor comprising al supporting member connected with the box, a Atongue member connected with the supporting member, said Atongue member having foldable side wings one of which is nearer the outer end of the tongue than the other, the combined tongue and spread wings being wider than saidv slot, the tongue and forward wingfwhen folded being insertible through the slot, said forward wing when unfolded lock to prevent withdrawal from the slot.

2. In combination with a paper box having a bottom formed with a slot'therein, an Aeasel therefor comprising a supporting member connected with the box and a tongue member connected with the supporting member, said tongue member having 'connected with the side thereof two foldable wings, one of which is nearer the outer end of the tongue that the other, said slot being of suoli size that said tongue together with the said wings are slidable through the slot when the wings are folded, the tongue and wings when unfolded being together of 'greater width than the slot, said wings being separated from each other whereby tongue and that portion ofthe tonguewith which it is immediately connected are passed through the slot into the interior of the box and said wingopened out, and the otherl wing.' is outside of the box and open d out the tongue will be locked against withdrawal'of the inner wingor pushing in of the outer wing.

3. In combination with a paper box, the bottom of which has a slot therein, an easel therefor comprising a supporting member connected with the box, `and a tongue member provided with foldable wings, said tongue with the wings when folded being' insertible in the slot, the combined tongue 'and wings when unfolded being wider than the slot, one of said wings being nearer the outer end of the tongue than another one of said wings, said two wings being separated from each other whereby the tongue may be engaged with the slot in suoli manner that one of the wings is on the out-side of the bottoni ofthe box while the other wing ison the insideof the bottom of the box.

et. In combination ri'ith a' paper box, a lnoclidown `easel attachment therefor, havl. In combination with a paper box hav` at one end a'hinged connection withthe box and having at its other end a tongue terminating'in a loc-king tab, the 1bottom of' the box being formed with a slot through Which the' tongue is slidable, the locking tab 'being of. awidth which normally prevents .it from beingv'drawn out through the slot and the tongue being formed with foldable Wing portions which when folded permit sliding movement of the tongue through the slot, and which when turned at an angle to the face of the tongue serve to prevent the tongue from sliding in through the slot.

-5.;In combination with a paper box, A-a foldlng easel attachment therefor, said box 'being 'formed with a slotin the bottom thereof, said. easel having` an extension portionwhichis slidable through said slot, and

which -When .pushedin permits the easel to.

be folded against the bottom of the boX, and

which can be drawn outwardly to .permit setting up thee sel, said extension portion having a tab'whi h normally limits the out- Wardl sliding 'movement to the predetermined set-up position of the easel, said extension also being formed withprojections which are capable of being turned at. an. angle to the plane' of said extension member to serveas a' lock aga-inst inward lsliding movement -of the extension member and prevent c0llapsible movement of the easel. f
